Grant Gustin Returns To Glee

TVLine is reporting that Grant Gustin is returning to "Glee" as Sebastian. No word on his storyline, but he will be back for multiple episodes.

Last season, Sebastian was after Blaine (Darren Criss), but Blaine was with Kurt (Chris Colfer). This season, things are different, as Blaine and Kurt have broken up. Does that mean Blaine and Sebastian will hook up?
